[Asia Fluid Network News] fire pump, as the name implies, the fire pump. Fire pump with a fully sealed, leak-proof, corrosion-resistant, etc., are widely used in environmental protection, water treatment, fire and other departments for pumping all kinds of liquids, is to create a leak-free, pollution-free civilized workshops, civilized factories ideal pump. So how can we buy a cost-effective fire pump? Next, Xiaobian share in this fire pump selection guide, model Daquan and the top ten brands, it is worth collecting! How to buy a cost-effective fire pump? Fire pump selection points 1, the fire pump flow and lift should be based on the project services to the fire water and water pressure requirements determined by calculation. 2, the selected fire pump should be the national fire product quality supervision and inspection agencies type test, and in line with "fire pump" GB6245-2006 requirements. 3, according to the characteristics of the project, the power supply and fire pump room location, area and fire water supply system, the specific circumstances of choice, to determine the type of fire pump. 4, the temporary high-pressure or stable high-pressure fire water supply system fire pump should be used one by one or prepared by a multi-purpose operating mode. The spare pump should be the same as the working pump, and the working capacity should not be less than one of the largest fire pumps in service. When the multi-use a prepared, should consider the pump flow superposition, the impact on the pump outlet pressure. 5, according to "Building Design Code of Fire Protection" (GB 50016--2006) provides: fire pumps should be set aside pump, its ability to work should not be less than the maximum of a fire pump. Spare pumps may not be provided when the outdoor fire fighting water volume at factories, warehouses, yard and storage tanks is less than or equal to 25 L / s or less than 10 L / s in buildings. Fire pumps should be guaranteed within 30 seconds after the start of the fire. Fire pumps and power machinery should be connected directly. 6, fire pump motor shaft power should meet the pump operating conditions (pump curve) work requirements. The pump performance curve without hump, fire pump stop pump pressure should not exceed 140% of the system design rated pressure, when the pump flow rate of 150% of rated flow, then the pump pressure should not be less than 65% of rated pressure .
